— OFSecureData: Add allowsSwappableMemory property
With this property, it's possible to specify whether the memory should
be protected from swapping or not. This makes it easier for e.g. the
crypto hash classes: They can now just always use OFSecureData without
wasting unswappable memory if it's not needed. (user: js, size: 1235) [annotate] [blame] [check-ins using]
